I don't really understand why would you even consider going deep if this is not something you have experience with or strong interest. Sure, it is good to know how some of the things work under the good, but you can be perfectly capable developer by reading docs and knowing how to use tools - without needing to know how to write them or how they do complex things under the hood. Take databases as example, network stack, etc. Just because a field is popular, doesn't mean you should switch to going deep into it. But that doesn't mean you shouldn't use it - it costs a few dollars to try it out and see whether it fits your workflow. If it does, this is great and you can be more productive and focus on stuff that you can solve and LLM can't, but if it doesn't, that is fine too.
